PIPE-COLLAR.

sPEcIFIcATIoN forming' para of Letters traitent No.6o8`,o6o, dated Julyas, 189s. `Application filed January 24, 1898, Serial No. 667,799. (Nomodel.)

' To if/ whom t may concern:

v drawings, forming a part of this specification,

scription.

My inventionrelates to` pipe-collars especally adapted for exposedpiperisers that' pass through finished ceilings, floors, and walls.

rThe object of the invention is to construct such a device in a simple,durable, and economic manner and so that the device may be expeditiouslyand conveniently applied to hot# water or steam supply, steam orhot-Water return, and air-vent pipes in`pipe-risers;without marring theceiling or wall.

A further object of the invention is to so constructthe device that itwill admit of eX` pansion and contraction and obviate cutting thetemplets, as the portions ofthe collar can be adjusted to suit any riserwhether out of4 line or square.

A further object of the invention'is to provide a pipe-collar which willadmit of the filling of fireproof material around the pipes and whichwill prevent the dropping of any dirt and the passing ot' anynoise orany bad odors from one iioor to another.

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth, and pointed outin the claims.

Reference is to be had to the accompanying in which similar charactersof reference indi` cate corresponding parts in all the figures.

Figure l is a verticalsection on the line 1 1 in Fig. 2 through aportion of the iioor and ceiling, illustrating the application of thedevice. device constructed for application to a ceiling, the pipespassing through the device being shown in horizontal section.V Fig. 3 isa horizontal section taken substantially on the line 3 3 of Fig. 1, andFig. 11 is altransversesection taken substantiall y on the line 4 lof 5oFig. 3.

A represents a section of flooring, D a por- Fig. 2 is a bottom planView of the` tion of the ceiling, and C the casing, vwhich eX- Be itknown that I, EDWARD J. IVIALLEN, of the city of New York, borough ofMamv hattan, in the county oi' New York and State of New York, haveinvented a new and use-, ful Improvement in Pipe-Collars, of which thefollowing is a full, clear, and exact de-` tends throughcorrespondingopenings made in the floor and in the ceiling, throughwhich casing the steamsupply pipe D is passed, the return-steam pipe D',and the air-vent D2. `The body of the device may be` given any desiredshape. Preferably, however, it is of i somewhat elliptical form and isin the nature of a plate 10, made in itwo sections a and ct',

yeach section of the body being provided with a marginal flange l1 andwith an inner opening 12. One section ofthe body is further providedwith lugs 13 at its ends, the said lugs being formedat the inner face ofthe section, and the lugs are arranged to extend over the correspondingsurface of the opposing sectionof the body, the two sections of the bodybeing connected by screws 14, which pass through the outer4 face of thesection Aoverlapped by the lugs 13 and into said lugs only when` thedevice is to' be applied to a ceiling; but when the device is to beapplied.

to a floor the screws 14 pass through and beyond the lugs and are madeof sufficient length to enter the floor, as shown at the upperportion'of Fig. 1.

Upon what may be termed the inner "face of the body lugs 15 are formedat the end at each side of the center, the lugs extending inwardly or indirection of the center, and at each side of each section, also upon theinner face, a lug 16 is formed, extending from the flange inwardly or indirection of the cenyter of the body.

`In connection with the body usually three clamping-plates 17, 18, and19 are employed, the clamping-plates 17 and 18 being at the plate 19 atthe center. The clamping-plates are held between the lugs 15 and 16 andthe. inner face of the body.

.The clamping-plate 17 is provided with an opening 17 a, adapted toreceive, for example, the steam-supply pipe D, and `spurs 17'b areformed at intervals at the margin of the said openingl to engage withthe said pipe and allow of the expansion `and contraction thereof. Theclamping-plate 1S is similarly provided with an opening 18, receiving,for example, the return-steam pipe D', and at the margin of this opening1S spurs 18b are also formed to engage with the end portions of the bodyand the clampingi pipe; but in the central clamping-plate 19 anuninterrupted opening 19a is formed, which is adapted to receive anair-vent D2.

The clamping-plate is provided with a cut 2O or is divided from one sideto the opening 17a. The clamp 18 -is similarly provided with a cut or adivision 21, and the central plate 19 also has a out or a division 22produced therein, extending; from one of its edges to the opening 19, asis clearly shown in Figs. 2 and 3. The clamping-plates are made of aspring material-as, for example, sheetbrass-and by. reason of the cutsmade therein the sections of the plates adjacent to the cuts may becarried in opposite directions and the several plates readily slippedupon the pipes they are` designed to receive. After the pipes haveentered the openings in the plates and the plates are released they willassume their normal position and be perfectly fiat.

The end plates 17 and 18 slide over or rest upon the central plate 19when the device is attached to a ceiling; but when the device isattached to the floor the central plate will rest upon the endclamping-plates, as shown in Fig. 1. To this end recesses 23 are made inthe central portion of 'each section of the body, as shown in Fig. 4,into which recesses the central plate 19 is introduced. Under thisarrangement the upper faces of the several lugs 15 and 16 may be in thesame horizontal plane.

When the device is to be used upon a ceiling, in order that the ceilingshall not be unduly marred or broken the screws 14 are not carried intothe ceiling, as heretofore stated. Instead of screws clamps E areemployed, these clamps consisting of two upright members 24, each havinga base member 25, the base members of the clamps being secured by screws26 or other fastening devices to the central lugs 16. The upper portionsof the members of the clamps diverge, and at the upper extremity of eachmember or section of a clamp a toothed jaw 27 is formed, the jaws facingin direction of each other.

In the application of the device to a ceiling a suitable opening is madeat opposite sides of the casing C to admit the, clamps, and the bodyportions of the clamps are forced upward, receiving between theirsections or members the casing C, the jaws 27 of the clamps firmlyengaging with the casing by reason of the clamp being made ofspringsteel or a similar material, as is fully illustrated in Fig. 4C.The clamps Will have sufficient hold upon the casing to maintain thedevice in the position required. In order that the clamping-plates shallnot have sufficient play to cause such displacement as to produce anopening in the device, projections 28 are formed upon the severalclamping'- plates, which by engagement with the walls of the opening 12in the body-plate will limit the side movement of the clamping-plates.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. Ina pipe-collar, a skeleton body-plate,clamping-plates having pipe-receiving openings, each clam ping-platebeing provided with a cut extending from an edge to the pipe-receivingopening therein, and means, substantially as described, for holding theclampingplates in the body-plate, as and for the purpose specified.

2. In a pipe-collar, the combination, with a body-plate, ofclamping-plates adjustably held in the body-plate, the said body-platebeing provided with pipe-receiving openings, and cuts extending from thesaid openings to the outer edge of the several plates, as and for thepurpose speciied.

3. The combination, with a body-plate constructed in detachablesections, the said sections being provided with lugs, of clampingplatesheld to slide in the body-plate between the said plate and its lugs, theclampingplates being of a ,spring material and provided withpipe-receiving openings, and cuts leading from the pipe-receivingopenings of the plates to the outer edge thereof, for the purposespecified.

'4. A pipe-collar consisting of a bod y-plate constructed in removablesections, and clamping-plates adj ustably and removably held in thebody-plate, the clamping-plates being of a spring material, endclamping-plates being mounted to slide in engagement with a centralclamping-plate, each clamping-plate having a pipe-receiving opening, andeach clamping-plate being likewise divided at a portion in its surface,the division extending from the pipe-receiving openings to the outeredges of the said plates, as and for the purpose specified.
